TDQS

B3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds real value beyond that by disclosing the shape of the result (cheapest price plus shop count per alternative), but says nothing about how many results come back, what the default limit implies, or what happens for a product with no similar items.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no filler; the resource and returned fields come first. It is efficient and readable, though the parenthetical gloss could have been spent on usage routing instead.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter read-only lookup with annotations and no output schema, the description covers purpose and result fields adequately. It is incomplete on the one thing an agent must decide unaided: when to reach for this over tb_variants, tb_compare, or tb_cheapest, and how the limit affects results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 50%: the 'product' parameter is documented in-schema as a UUID or torob.com URL, but 'limit' carries no description beyond type and 1-50 bounds. The description mentions neither parameter, so it does not compensate for the undocumented limit or clarify whether the shop count/price apply per alternative.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the resource precisely: products that Torob classifies as similar, explicitly glossed as 'alternatives in the same class', and the returned fields (cheapest price, shop count). It is clear what the tool retrieves, though it never contrasts itself with nearby siblings such as tb_product, tb_variants, or tb_compare.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit when-to-use guidance and no named alternative. An agent must infer from the word 'similar' that this is the right call versus tb_variants (different variants of one product) or tb_compare (side-by-side comparison), with no help from the description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
